            <p>Included are some useful helper classes for working with
            MSI and MSP packages:</p>
            <ul>
            <li><p><a href="ms-its:MMLRef.chm::/Microsoft.WindowsInstaller.InstallPackage.html"
            ><strong>InstallPackage</strong></a> - extends the Database class to provide powerful
            package-based operations such as:</p>
            <ul>
                <li>direct extraction of files to uncompressed source 
                path 
                <li>updating files from uncompressed source path back 
                into the compressed source for the package (including updating file 
                metadata) 
                <li>applying a patch directly to the package 
                <li>consolidating a package with uncompressed source files or multiple msm-cabs
                into a package with a single compressed cabinet</li>
            </ul>
            <P></P>
            <li><p><a href="ms-its:MMLRef.chm::/Microsoft.WindowsInstaller.InstallPathMap.html"
            ><strong>InstallPathMap</strong>, <a href="ms-its:MMLRef.chm::/Microsoft.WindowsInstaller.InstallPath.html"
            ><strong>InstallPath</strong></a> - represent the directory structure
            of an installation package, including file, component, and directory source and target
            install paths.  Accessible by file, component, or directory keys; searchable by
            filename.</p>
            <li><p><a href="ms-its:MMLRef.chm::/Microsoft.WindowsInstaller.PatchPackage.html"
            ><strong>PatchPackage</strong></a> - allows convenient access to patch properties,
            and analysis and extraction of transforms</p></li>
            </ul>
            <p><br/></p>
            <p>These classes are in the Microsoft.WindowsInstaller.Package.dll assembly.</p>
